Spellstitching fun

[Little Brother]

Is there any reason why you can't just Wis Damage a Necropolitan down to zero, Spellstitch it(I see no time given for stitching), then restore the damage? I mean, Wis 0=0 XP spent. Am I missing something?

Not sure how official this is, but I'm pretty sure the SLAs the Spellstiched gets are chosen at Crafting.

Thus a Necropolitan with 0 Wisdom at the time would get 0 SLAs, while still having to deal with the CR/LA increase.
